While OnBase supports the 32-bit and 64-bit versions of Microsoft Office 2021, Hyland Software recommends that customers only install the 32-bit version of Microsoft Office 2021. For most users, the 64-bit version of Microsoft Office 2021 does not provide additional performance benefits.
Microsoft provides the following guide to assist with choosing the correct version of Microsoft Office for your organization (http://support.office.com/en-us/article/Choose-the-32-bit-or-64-bit-version-of-Office-2dee7807-8f95-4d0c-b5fe-6c6f49b8d261?CorrelationId=165c464e-6fb1-4532-83ad-7537787fd680&ui=en-US&rs=en-US&ad=US).
Separate versions of the Office Business Application for 2021 and Integration for Microsoft Outlook 2021 modules are available that support the 64-bit version of Microsoft Office 2021. The 64-bit versions of these modules have limited functionality, though, due to some components which are not 64-bit compatible.
The following are limitations when using the 64-bit versions of the Office Business Application for 2021 and Integration for Microsoft Outlook 2021 modules:
-
The ClickOnce installer is not supported.
-
The embedded Unity Document Viewer cannot display Microsoft Office documents. The Office Business Application for 2021 will be used to open all Microsoft Office documents. The Office Business Application for 2021 is required to view Microsoft Office documents from the Integration for Microsoft Outlook 2021.
-
Topaz signature pad functionality, which is part of the Signature Pad Interface module, is not available.
-
Document scanning and acquisition is not available.
-
The Document Composition preview window, which may be displayed after composing a new document using the Document Composition module, is not available.
-
Send To | Mail Recipient functionality using the Novell GroupWise email client is not available.
OnBase does not support mixed 32-bit and 64-bit Microsoft Office installations with the Office Business Application and Integration for Microsoft Outlook modules.
